Cutting device and printing apparatus

Abstract

A cutting portion (cutting device) includes a fixed blade that extends in an intersecting direction (X axis direction) intersected with a transport direction transporting a roll paper, and a round blade that cuts the roll paper by relatively moving in the intersecting direction (X axis direction) with respect to the fixed blade in a state of being abutted on the fixed blade, in which the fixed blade extends over a portion of a range where the round blade relatively moves, and the round blade is in a separation state of being separated from the fixed blade in the transport direction when entering a region facing the fixed blade (cutting operation region) from a region not facing the fixed blade (standby region).

What is claimed is: 
     
       1. A cutting device comprising:
 a first cutting member that extends in an intersecting direction intersected with a transport direction transporting a medium; 
 a second cutting member that cuts the medium by relatively moving in the intersecting direction with respect to the first cutting member in a state of being abutted on the first cutting member; and 
 a support portion that supports the second cutting member, 
 wherein the first cutting member extends over a portion of a range where the second cutting member relatively moves, and 
 the support portion is configured to be rotated such that the second cutting member is in a separation state of being separated from the first cutting member in the transport direction when entering a region facing the first cutting member from a region not facing the first cutting member. 
 
     
     
       2. The cutting device according to  claim 1 , further comprising:
 a guide portion that guides the second cutting member in accordance with a movement from the region not facing the first cutting member to the region facing the first cutting member, 
 wherein the second cutting member is changed from the separation state to an abutting state of abutting on the first cutting member by sliding contact between the guide portion and the support portion when the second cutting member moves in the intersecting direction. 
 
     
     
       3. The cutting device according to  claim 1 ,
 wherein the second cutting member is a rotatably supported disk-shaped round blade. 
 
     
     
       4. A printing apparatus comprising:
 a transport portion that transports a medium in a transport direction; 
 a printing portion that performs printing on the medium to be transported; 
 a platen that supports the medium in a printing region where the printing is performed; 
 a first cutting member that extends in an intersecting direction intersected with the transport direction; 
 a second cutting member that cuts the medium by relatively moving in the intersecting direction with respect to the first cutting member in a state of being abutted on the first cutting member; and 
 a support portion that supports the second cutting member, 
 wherein the first cutting member extends over a portion of a range where the second cutting member relatively moves, and 
 the support portion is configured to be rotated such that the second cutting member is in a separation state of being separated from the first cutting member in the transport direction when entering a region facing the first cutting member from a region not facing the first cutting member. 
 
     
     
       5. The printing apparatus according to  claim 4 , further comprising:
 a platen unit that includes the first cutting member or the second cutting member and the platen, 
 wherein the platen unit is movable to a first position where the platen faces the printing portion and a second position where the platen is more separated from the printing portion than in the first position. 
 
     
     
       6. The printing apparatus according to  claim 4 ,
 wherein the printing portion includes an ejection head that moves to a home position deviated from the printing region, and 
 a region where the second cutting member does not face the first cutting member is provided on the same side as the home position in the intersecting direction.
